Finally, it is important to note that while sputtering engines may provide good acceleration performance when properly maintained, they are not as efficient as other types of internal combustion engines such as turbocharged or direct injection systems which offer better fuel economy and lower emissions levels at higher speeds than sputtering engines do at lower speeds. Engine runs rough and backfires under throttle - Lawn Mower Forum This component, part of your vehicles exhaust system, works by converting harmful compounds like carbon monoxide, nitrous oxide, and hydrocarbons into less harmful compounds such as water and carbon dioxide. I have to run it for about 10 min, get it warm, then with the blades engaged and full speed, it'll stumble and backfire, seems to get really rich, or miss, you can smell gas when it starts this. In order to improve fuel economy in such cases, it is important to identify and address the underlying cause of the sputtering engine. If any of these are missing or incorrect, the cylinder combustion will not be done correctly, and no power will be created. The car idles and starts fine.
